本文给出的代码用于比较 比较Java中的FileInputStream与DataInputStream类 的性能。

部分代码展示：
  try {
    // Open the file that is the first command line parameter
    FileInputStream fstream = new FileInputStream(args[0]);
    // Convert our input stream to a DataInputStream
    DataInputStream in = new DataInputStream(fstream);
    // Continue to read lines while there are still some left to read
    while (in.available() !=0) {
      // Print file line to screen
      System.out.println (in.readLine());
    }
